Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Back flow into the left atrium would be caused by a faulty (not working properly) valve; which one?
A
aortic semilunar
B
pulmonary semilunar
C
tricuspid
D
bicuspid
Explanation: 

Detailed explanation-1: -In aortic valve regurgitation, the aortic valve doesn’t close properly, causing blood to flow backward from the body’s main artery (aorta) into the lower left heart chamber (left ventricle).

Detailed explanation-2: -BAV is present at birth (congenital). An abnormal aortic valve develops during the early weeks of pregnancy, when the baby’s heart is developing. The cause of this problem is unclear, but it is the most common congenital heart defect. BAV often runs in families.

Detailed explanation-3: -Mitral valve: Allows blood to flow into the left ventricle; prevents blood from flowing back into the left atrium.

Detailed explanation-4: -What are the complications of bicuspid aortic valve? An untreated bicuspid aortic valve can eventually lead to symptoms of heart failure. These include shortness of breath, fatigue, and swelling. Also, an aortic aneurysm might develop downstream from the aortic valve and can lead to bleeding or rupture.

Detailed explanation-5: -They allow blood to flow from the lungs into the left atrium. And they prevent backward flow from the left ventricle to the left atrium.
